"But Manziel, to many teams right now, would be undraftable because they're scared of his mood swings and off-field questions. But it only takes one team out of 32 to fall for him. And some team will, unless he self-destructs between today and draft day," King wrote.

The Heisman Trophy winner is coming off a game in which he accounted for a school record 464 passing yards against top-ranked Alabama.

Manziel critics believe that his off-field exploits, which have included an arrest, an NCAA investigation numerous social-media miscues, will impact his draft stock.

Some NFL scouts are also concerned about his size, as Manziel is listed at 6-1 but that may be a stretch.

Of course Manziel could make all the draft talk a moot point if he decides to remain at A&M following the season. He still has two years of eligibility remaining if he elects to stay in school.
